Job Summary:

We are seeking a highly skilled and creative Penetration Tester with over 6 years of experience to join our Offensive Security team. The successful candidate will have deep expertise in identifying vulnerabilities in enterprise infrastructure, web applications, Active Directory environments, and cloud platforms (AWS, Azure, GCP) — all without prior internal knowledge of the systems being tested.

This role demands a think-outside-the-box mindset, capable of discovering novel attack vectors that others overlook, with a strong focus on making meaningful, measurable impacts on organizational security.

Key Responsibilities:


• Perform comprehensive black box penetration testing of:

o Enterprise networks and internal infrastructure

o Web and mobile applications

o Active Directory environments (Kerberos, LDAP, domain trusts, etc.)

o Cloud platforms including AWS, Azure, and GCP


• Identify and exploit misconfigurations, logic flaws, privilege escalations, and other high-impact vulnerabilities.


• Simulate real-world attack scenarios such as credential attacks, lateral movement, and privilege escalation in AD/cloud hybrid environments.


• Document detailed technical findings, risk ratings, proof-of-concept exploits, and remediation strategies.


• Collaborate with internal teams to validate fixes and ensure secure configuration post-remediation.


• Stay up to date with threat actor tactics, techniques, and procedures (TTPs).


• Contribute to internal tooling, red team exercises, and security testing methodologies.


• Mentor junior team members and assist in strategic planning of offensive security initiatives.

Required Skills and Qualifications:


• 6+ years of proven experience in black box penetration testing.


• Strong expertise in Active Directory testing, including attack paths, domain privilege escalation, and lateral movement.


• Experience in cloud security testing across AWS, Azure, and GCP environments (IAM roles, misconfigured services, metadata exploitation, etc.).


• Solid understanding of network protocols, web application security, OWASP Top 10, and API exploitation.


• Proficiency with tools such as Burp Suite, Nmap, Impacket, BloodHound, Mimikatz, Metasploit, and PowerView etc.


• Scripting ability in Python, PowerShell, or Bash for exploit development and automation.


• Strong analytical and creative problem-solving skills.


• Excellent report writing and verbal communication abilities.

Preferred Certifications (Good to Have):


• OSCP / OSEP / CRTP / CRTE / OSED / OSWE / GPEN / AZ-500 / AWS Security Specialty


• Microsoft or cloud-specific red team certifications are a plus

What We're Looking For:


• A strategic attacker's mindset who can go beyond surface-level vulnerabilities.


• A technical leader who can assess modern hybrid infrastructures with precision.


• A contributor who can deliver real-world risk insights, not just findings.
